inner side,-or.coveredwith. silveredlass,

formed with a silvered surface covered with 'transparent glass, in anyof the known Ways of forming the surface of rellectors. G represents thesupport, which is formed of gaspipe in the usual manner, and serves toconduct the gas to the burners, as well as tosustain the recctor. Theburners D are attached to `a circular pipe, C, communicating with G, andlocated just within the upper edge 'of the truncated cone A. The burnersare disposed at equal distances around the circle, and preferably'project inwardly toward the center, but they may be placedperpendicularly., fithin the truncated cone is centrally suspended, byattachments from pipev C, or in any suitable manner, an inverted cone,E, the .base of which is inthe plane ofthe up- 'per base of thetruncated cone A. The object of this central cone is to increase theredection of light'downvvard by reflecting such rays as are radiatedtoward the center. 'lhc Y space between the upper edge of the truncatedconeA and the base ot' the innercone E should be such that the gas-llamewhen projecting horizontally will nearly cross and fill it withoutprojecting over or upon the inner cone, so as to burn or unduly heat it.Above this system of reflectors is placed a second reflector, B, formedof a truncated hollow cone of flatter shape, and centrally' perforatedto allow the gases ot' combustion to escape upward; -The object ot' thissecond reflector is to collect such rays as are radiated upward,

and to project theml dou-'nward with as little l loss as possible. Theangle of the Hare should be so arranged that the light relectcd shalltake directions as nearly as possible ,parallel to the sides of thelower cones, in order to avoid infringing on them and casting shad.

ws oi' said lower cones.

1n constructing'my reectors, regard is had to the extent of the area tobe illuminated.v 1f it be small,as in the case of show-windows, theflare of the cones should be so arranged as to confine the body of lightwithin the area vto be illuminated. In public halls or saloons,

where it is desirable to disperso the rays` over a larger area., and notconcentrate them, the flare should be expanded. The dimensions and thenumber of gas-jets employed can also be varied at pleasure. 'lhe centralcone'E is not absolutely necessary, as, where small arcas are to beilluminated, one or two gasjets are sutlicient, and the dimensions canthen he so contracted that the flame will cover nearly the whole openingoccupied by the central cone.

I claim as my invention- 'lhe improved reflector herein described,consisting of the'retlecting hollow truncated cones A and B, the centralreflector E, and the gas burners or jets, one or more, located. asdescribed, for the purpose specified.
